This standard BS EN ISO 24459:2023 Determination of uranium content in samples coming from the nuclear fuel cycle by L-absorption edge spectrometry is classified in these ICS categories:
27.120.30 Fissile materials and nuclear fuel technology
This document specifies a method for the determination of uranium concentrations in nitric acid or TBP-DILUANT (for example TBP-kerosene) solutions coming from the nuclear fuel cycle. The method is applicable — for process control of solutions, free of suspension, which contain between 10 g/l to 300 g/l uranium, and — for high accuracy purposes (Safeguards) to nitric acid solutions, free of suspension, which contain between 100 g/l and 220 g/l uranium.
